Rod end FLURO GASW 5 – M5 male, right-hand, maintenance-free PTFE (uniball)
- Rod end (uniball) FLURO GASW 5 with M5x0.8 right-hand male thread and 5 mm bore. Maintenance-free, PTFE liner, load capacity 4.3 kN. For motorsport and machinery.
FLURO GASW 5 rod end – M5 right-hand male thread, 5 mm bore, maintenance-free (PTFE)
FLURO GASW 5 is a maintenance-free rod end (also referred to as a rose joint, spherical rod end bearing, or male uniball) with an M5 right-hand male (external) thread and a 5 mm ball bore diameter. It supports a static load rating up to 4.3 kN and a dynamic load rating up to 7.5 kN, and thanks to its steel / PTFE sliding contact surface, it requires no lubrication throughout its entire service life.
This rod end belongs to the GASW series manufactured by the German company FLURO-Gelenklager GmbH, produced in dimension series K in accordance with DIN ISO 12240-4. This series is engineered for operation under dynamic loads, making it ideal for motorsport, mechanical engineering, and any application where a linkage must compensate for misalignment and operate without play.

Construction and materials
Housing (body with threaded shank)
The housing in size 5 is CNC-turned from free-cutting steel 9SMnPb28K and zinc-plated for corrosion protection. In the GASW series, housings up to and including size 12 are turned from free-cutting steel, while sizes 14 and above are forged from heat-treated steel.
Bearing liner
The bearing liner is made of free-cutting steel with a bonded PTFE sliding layer. This liner ensures maintenance-free operation and zero clearance (play-free performance).
Ball (inner ring)
The ball is manufactured from 100Cr6 (AISI 52100) bearing steel – hardened, ground, and polished.
Applications
GASW series rod ends are used in linkages that transmit axial forces along the rod while allowing angular misalignment. Typical applications for the M5 size include:
- throttle linkages and lightweight control rods,
- position sensor and suspension travel sensor linkages,
- light-load adjustment mechanisms and levers,
- lightweight tie rods and aerodynamic element supports,
- karting and scale modeling,
- joints in automation systems, small actuators, and precision instruments.
Selecting the proper rod end for a specific joint must take into account actual operating loads and the required safety factor – this is the responsibility of the designer or installer.
Installation guidelines
- A 5 mm (M5) bolt or pin passes through the ball bore.
- Secure the threaded shank using an M5 locknut (jam nut).
- The threaded shank should be screwed in to a depth of at least 1.5 times the thread diameter, i.e. a minimum of 7.5 mm.
- Do not lubricate the rod end – grease and oils degrade the performance of the PTFE liner.
- To utilize the full misalignment angle, high-misalignment (tapered) spacers should be fitted on both sides of the ball.
Frequently asked questions
What thread does the FLURO GASW 5 rod end have?
The FLURO GASW 5 rod end features an M5 male (external), right-hand thread. The thread length is 19 mm.
What bolt fits the bore of the GASW 5 rod end?
The ball bore diameter is 5 mm, so it accepts an M5 (5 mm) bolt or pin.
What load rating does the FLURO GASW 5 support?
The maximum static load rating is 4.3 kN (967 lbf), and the dynamic load rating is 7.5 kN (1686 lbf).
Does the GASW 5 rod end require lubrication?
No. The rod end is maintenance-free – the bearing liner has a PTFE sliding layer that must not be lubricated. The rod end has no grease nipple.
What is the difference between GASW 5 and GALSW 5?
GASW 5 has a right-hand thread, whereas GALSW 5 has a left-hand thread. Pairing right-hand and left-hand rod ends on opposite ends of a single tie rod allows turnbuckle length adjustment without disassembly.
What is the tilt angle of the GASW 5 rod end?
The ball tilts by 13° in each direction, giving a total misalignment angle of 26°.
What materials is the FLURO GASW 5 rod end made of?
The housing is turned from free-cutting steel and zinc-plated, the liner is free-cutting steel with a bonded PTFE layer, and the ball is hardened, ground, and polished 100Cr6 bearing steel.
Is the price for a single piece?
Yes, the price is for 1 piece of the FLURO GASW 5 rod end.
